In my ubuntu some libs may mismatch. I used ubuntu additional repo 

kdevelop 5.2.2 (http://ppa.launchpad.net/blaze/kf5/ubuntu/pool/main/k/kdevelop/)

I'm trying to open project saved on server by fish protocol.
I can do this with success when I open kdevelop, create a new session and then open project in this session by "Add project to current session".

When I try to open the project in another session "Open session My project" then kdevelop crash.

Debug:
